Description
Product Overview
The RAB Lighting Field Adjustable LED Corn Cob is a high‑efficiency, low‑maintenance lighting solution designed for demanding industrial and scientific environments. Constructed from a robust aluminum housing with a high‑temperature resistant polymer lens, the unit delivers consistent, flicker‑free illumination while withstanding the rigors of dry or damp locations. The lamp offers three wattage settings—12W, 18W, and 27W—allowing users to fine‑tune output to match specific lighting requirements without sacrificing energy savings. In addition, the selectable correlated colour temperature (CCT) range of 3000K, 4000K, and 5000K provides flexibility for tasks ranging from detailed inspection work to general area lighting.
Engineered for ballast‑bypass operation, the corn cob operates directly from a 120‑277V line voltage, eliminating the need for external ballasts and reducing overall system complexity. Integrated 4kV surge protection safeguards the LED array against voltage spikes, extending product lifespan and ensuring reliable performance even in environments with fluctuating power quality. The unit complies with UL and IEC standards for safety and performance, making it a trusted choice for professional installers.

Usage
Designed for versatility, this LED corn cob excels in a variety of applications. In manufacturing plants, it provides bright, uniform lighting for assembly lines, inspection stations, and quality‑control areas where colour accuracy and shadow‑free illumination are critical. In agricultural settings, the lamp’s adjustable wattage and CCT enable growers to create optimal lighting conditions for greenhouse crops, supporting photosynthetic efficiency while minimizing energy consumption.
Because the fixture is rated for fully enclosed dry or damp locations, it can be installed in ceiling‑mounted fixtures, wall‑mounted housings, and recessed enclosures without the need for additional ventilation. The compact form factor allows for retrofitting into existing HID fixtures, offering a seamless upgrade path for facilities seeking to replace legacy metal‑halide or sodium lamps. Its low heat output and sealed design also make it suitable for hazardous environments where spark‑free operation is required.

FAQ
Can this lamp be used in existing HID fixtures?
Yes. The corn cob is designed as a direct replacement for 125W metal‑halide or sodium HID lamps. Because it operates on ballast‑bypass, you simply remove the old ballast and install the LED unit, connecting it to the existing line voltage.
What is the expected lifespan of the LED corn cob?
The lamp is rated for up to 50,000 operating hours, which typically translates to more than five years of continuous use in most industrial applications.
Is the lamp suitable for damp or wet locations?
The unit is rated for fully enclosed dry or damp locations, making it appropriate for environments with occasional moisture exposure, such as greenhouse ceilings or industrial wash areas.
How does the surge protection work?
Integrated 4kV transient voltage suppressor (TVS) diodes clamp voltage spikes, protecting the LED chips from damage caused by sudden surges, thereby preserving performance and extending lifespan.
What warranty does RAB Lighting provide?
RAB Lighting offers a standard 3‑year limited warranty covering defects in materials and workmanship, along with access to technical support for installation and troubleshooting.
